OIL-STOVE CHIMNEY.

Specification of Letters Patent.

Patented Mar. 30, 1920.

Application filed September 21, 1918. Serial 'No. 255,111.

To all whom it may concern:

Be it known that I, LOREN D. MASON, a citizen of the United States,residing at Kokomo, in the county of Howard and State of Indiana, haveinvented new and useful Im' provements in Oil-Stove Chimneys, of whichthe following is a specification.

This invention relates to oil stove chimneys, the object in view beingto provide a practical, economical and reliable chimney for use inconnection with oil stoves, whereby heat is conserved and more evenlydistributed upon the bottom of a vessel or utensil of any kind placedover the chimney.

With the above and other objects in view, the invention consists in theconstruction con'ibination and arrangement of parts, as hereindescribed, illustrated and claimed.

In the accompanying drawing:

Figure 1 is a side elevation of the improved chimney.

Fig. '2 is a vertical section through the same.

Fig. 3 is a top plan view of the chimney.

Fig. 4L is a bottom plan view thereof.

The improved chimney comprises a hollow cylindrical body 1 ofpractically uniform diameter from top to bottom. At the bottom, thechimney is formed with an inwardly extending annular flange 2 adapted torest upon the rim of an oil burner, said flange being formed withperforations 3 to provide for the necessary draft and supply of air tothe burner. At a suitable elevation above the bottom, the body 1 isformed with a door opening at which is adapted to be guides being openedand closed by means of a horizontally slidable arcuate door 5 having aglazed observation opening 6 and provided with a suitable operatinghandle 7, said door being slidable between arcuate guides 8, said formedof strips of sheet metal which are suitably offset as shown and rivetedor otherwise secured to the body 1.

Adjacent to its top, the body 1 is formed with an annular bead 9 formingan annular rest or shoulder for an upwardly flaring rim 10. The upwardlyflaring rim 10 prevents Located centrally within the rim is a heatdeflecting disk 11 formed with perforations 12 to allow the heat toreach the center of the superimposed vessel or utensil. Said' heatdeflecting disk is supported by means of a diametrically extending strap13, the opposite extremities of which are secured by fastening means 1%to the rim 10. Said deflector directs a portion of the heat outwardly soas to act against all portions of the bottom of the vessel or utensilplaced above the supporting rim.

The chimney above described is admirably adapted for use in connectionwith a cooking stove and may be used for all kinds of cooking, bakingand laundry work. In economy and efficiency it has been found to be farsuperior to all devices of a similar character now on the market as faras I am aware.

I claim:

1. A chimney for the purpose specified, comprising a hollow cylindricalupright body of substantially uniform diameter throughout, an internalannular flange at the bottom of said body formed with perforations, anupwardly flaring rim at the top of said body, said rim being imperforatethroughout its entire area and servingas an air current protector, and aperforated disk shaped heat deflector located centrally of and supportedby said rim adjacent to the bottom of the latter.

2. The combination with the chimney of an oil stove, of an upwardlyflaring rim located on the top of the chimney said rim being imperforatethroughout its entire area and serving as an air current protector andalso as a means to distribute heat rising through the chimney, and aperforated disk shaped heat deflector located centrally of and supportedby said rim adjacent to the bottom of the latter.

In testimony whereof I aifix my signature.

LOREN D. MASON.
